3.5 - Powering up the X3-SP
When mains power is supplied, the power supply automatically detects the supply voltage
and adjusts itself accordingly. Once the display has gone through the “initializing” stage,
the screen will show the unit name and current preset recalled, and is then ready for use.
Important Note: When connecting the X3-SP or X3-DFSP to mains power supplies,
always connect the PowerCON first, and then connect to the mains supply. Similarly when
disconnecting, always disconnect from the mains supply first. Failure to do this can cause
arcs within the PowerCON connector, which can cause the amplifier to detect a fault and
require resetting.
Electrical Safety Issues
Please pay close attention to the following electrical and safety issues:
a) The X3-SP and X3-DFSP require grounded mains outlets. Always use a grounded
outlet and plug.
b) Never use a ground-lifting adapter or cut the earth pin or cable.
c) Do not exceed the 20-amp current capability of the PowerCON input connector.
When connecting multiple loudspeakers together, consider the current
requirements of all loudspeakers in the circuit – including the first one.
d) Ensure that the AC power connector for the mains outlet has the appropriate rating
for the planned total current draw, and is also suitable for the area the loudspeaker
is being used in.
e) Do not use the loudspeaker if the power cables are frayed or broken.
f) Keep all liquids away from the units to avoid hazards from electrical shock.
